Impact of selected work condition factors on quality of manual assembly process

This article presents the investigation of selected work environment factors with regard to the quality of manual assembly process. It describes the research carried out in a natural work environment and conditions in a factory producing car wire harnesses. It has been pointed out that only a few work condition factors have a significant influence on the assembly process's quality. The results of the experiments have proved the hypothesis that, between the two important work factors (noise level and work monotony), there is a significant interaction with respect to their impact on the assembly quality process.
